Tracking wildlife is a tough job. Take the case of a one-eared leopard named Pavarotti.
Kasim Rafiq, a wildlife biologist at Liverpool John Moores University. "So I used to get up at the crack of dawn, follow his tracks and try and find him. So one day, I went out, and I was looking for him. And his tracks took me off road through this woodland area...and..."
Before he knew it, the wheel of his Land Rover was stuck in a deep hole. He wasted several hours getting it out. And then, on the way back to camp, he came across some local tour guides and their safari (观赏野兽的旅行) guests, who'd had way better luck spotting Pavarotti. "Basically, they laughed and they talked to me that they'd seen him that morning."
Rafiq then realized that tourist wildlife sightings might be an untapped source of information about wild animals.
So he and his team worked with a safari lodge in Botswana to analyze 25,000 tourist photographs of wildlife. They compared those data to the estimates they made with traditional wildlife biology methods.
It turned out that the estimates from tourists' photos were just as good as those gleaned (四处搜集) from traditional methods. And the tourists were actually the only ones to see elusive (难以捉摸的) leopards — the researchers would have missed the cats without the citizen science data. The results are in the journal Current Biology.
The idea is not to put wildlife researchers out of a job. "The reality is there are so many interesting things we still have to find out about these large carnivores (食肉动物) and so many conservation (保护) projects that need to be carried out that we don't have the time or resources to do them all." And tourist photos might help make sure that all the local carnivores are spotted.
Thanks for listening for Scientific American-60-Second Science. I'm Christopher Intagliata.
